RE-ENFORCED PAPER FABRIC.

SPECIFICATION forming part of Letters Patent No. 320,614, dated June 23, 1885.

Application filed December 7, i883.

T0 aZZ whom it may concern.-

Be it known that I, J OSEPH H. BEALE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Reenforced Paper Fabrics, of which the following is a specification.

The object of my invention is to produce a paper fabric with thickened strips formed of paper pulp, and run upon'the paper pulp sheet at the same time it is formed, and cal endered, so as to form a paper fabric having homogeneous thickened ribs or strips extending in any desired direction across or through-' out the width or length of the same, whereby the fabric may be strengthened at such thickened portions orpoints, or homogeneous staystrips, as may be desired, to render the same more valuable for various purposes requiring a paper fabric having re-enforce stay-strips or strengthening pieces applied at certain points or at intervals throughout the length or width of the paper web or sheet, as hereinafter more fully described, and set forth in the claims.

Figure 1 represents a sheet of paper fabric constructed according to my invention. Fig. 2 represents an end view of the same.

A represents a web, strip, or sheet of paper of any length or width desired, and formed of any kind, quality, or color of pulp known, and when formed in the pulp-sheet there is simultaneously formed and united therewith the thickened strips or portions 13, ofsimilar pulp, or of a different quality, or of a stronger or longer fiber, or of the same color, or of a different color, as may be desired, to form or produce a paper fabric having homogeneous strips, stay, or re-enforce or thickened strips or portions, united in the manufacture or pulp state, and formed upon one or both sides of the main sheet and extending longitudinally, diagonally, or at right angles, or across the main sheet, or upon the same, in any desired manner, to strengthen the main sheet when produced or finished by calendering, or in any suitable manner, to form a paper fabric having re-enforce or thickened strips at intervals (No model.)

so as to strengthen the same at the said strips, re-enforce stays, or other thickened portions thus formed. The main body or sheet of paper A may thus be formed of very short fiber or of a cheap quality of pulp, and the strips or re-enforce portions B of a long fiber or better quality of pulp, whereby the former is held together and strengthened in the direction the latter are formed, or the thickened portions or stay strips-B are united with the sheet A lengthwise.

The paper fabric thus formed may be used in the manufacture of carpet-linings with great advantage and for a variety of purposes.

The re-enforced paper fabric thus constructed or formed as a new article of manufacture linings, floor coverings and like purposes where strength and cheapness are essential features in the area of the product.

It will be understood that in order to form such re-enforced paper fabric it will be neces sary to employ two sets of cylinder papermolds, one, as heretofore, for the mainsheet, and one to form the said re-enforce strips, which is accomplished by simply applying to deckel cloth at intervals, leaving such width of space intervening uncovered to take up the pulp to form the re enforce strips, which unite with the main sheet formed simultaneously by the main cylinder, as heretofore employed, the width of such main sheet being governed by deckel-cloths, applied thereto at each end, as heretofore.

Having thus described my invention, what I claim is- 1. As an improved manufacture, a paper fabric having continuous re-en forced strips extending across the fabric, and formed integral therewith.

2. A paper fabric, having continuous re enforced strips formed of a different fiber and united in the pulp with the sheet, as set forth.
